Scott Dixon continued his ascent up the practice charts for the Indianapolis 500, setting the fastest laps of Tuesday's slightly shortened session.
Posting the third best lap of Saturday's practice and the second best of Sunday's, Dixon dethroned Helio Castroneves at the top of the charts on Tuesday with a 39.7265 second lap. Castroneves, for his part, was eighth, only three tenths of a second off, and still maintains the fastest lap of any practice session, a 39.6395 that he turned on Sunday.
Mario Moraes, who has been fast at Indianapolis each of the past two years, ranked second, about a tenth of a second off Dixon's pace, while Marco Andretti ranked third. The top 21 cars only had about half a second between them, and of the 36 who practiced, only Sebastien Saavedra and Milka Duno were more than a second off the pace.
Simona de Silvestro continued to impress by turning a 40.147 second lap, good for 10th overall and best of both the rookies and females in the field. Jay Howard was the next best rookie, his 40.234 time good for 15th; the next best woman was Sarah Fisher in 29th. Three of the women - Fisher, Danica Patrick, and rookie Ana Beatriz - ranked 29th, 30th, and 31st, respectively, on the charts.
The fastest driver with an Indy-only ride was Paul Tracy, who came in 11th with a 40.175 second lap. Next in that category were A.J. Foyt IV, who came in just behind Tracy in 12th, and John Andretti in 13th.
Fisher completed the fewest laps of anybody, with only 15. Alex Lloyd had the most laps completed of any driver, with a high of 81.
KV Racing Technology experienced two incidents over the course of the day, with Moraes spinning on his way out of pit lane and E.J. Viso wrecking at the end of the session. Viso was transported to Methodist Hospital for evaluation.
